Pest Infestations 

Pursuant to Administrative Code §27-2017.8 of Local Law 55 (2018), property owners have an obligation to maintain their properties free of pests.

Property owners must use integrated pest management practices to remediate the presence of pests. Any dwelling unit or common area found to have mice, rats, and/or cockroaches will result in a “Class C” violation. All other pest infestations will result in a “Class B” violation.

Required integrated pest management practices include:

  • Inspecting for, and physically removing pest nests, waste, and other debris by High-Efficiency Particulate Air (HEPA) vacuuming;

  • Eliminating points of entry and passage for pests by repairing and sealing any holes, gaps or cracks in an apartment using durable material such as sealant and plaster;

  • Eliminating sources of water for pests by repairing plumbing materials that accumulate water or leak.

When certifying a correction for pest violation(s), you must complete the Certification of Correction for Pests.

To learn more about the required integrated pest management practices, you can read HPD’s Guide to Local Law 55 of 2018 – Integrated Pest Management Practices for Mice, Cockroaches, and Rats.

Please note: Pursuant to Administrative Code §27-2017.8 of Local Law 55 (2018) any pesticide applied to eradicate the presence of pests must be applied by a pest professional licensed by the New York State Department of Environmental Conservation (DEC).

Local Law 61

Under current New York State law (Labor Law Article 32), an owner or agent who hires a third party to conduct mold assessment and remediation must hire licensed mold contractors. Licensed mold contractors are required to adhere to the minimum work standards outlined below. 

Please note that mold assessors and mold remediators cannot work under the same contracting firm. They are required to be independent from one another. 

Property owners who do not hire a third party are strongly advised to follow the NYC Department of Health and Mental Hygiene's Mold Guidelines to ensure proper remediation and minimize health concerns for workers and tenants related to mold conditions and violations.

Be advised that as of January 1st, 2019, Local Law 61 of 2018 establishes filing requirements for mold contractors that carry out mold assessment and mold remediation for buildings that contain 10 or more dwelling units or are located on a zoning lot that contains 25,000 or more square feet of non-residential floor area, where the work to be performed involves working in project areas with mold greater than or equal to 10 square feet of mold.


Under this law, licensed mold contractors are required to provide the property owner with filing receipts as proof that the proper documents, under Article 32 of the New York State Labor Law, were filed.

These forms can be found by visiting the New York City Department of Environmental Protection's Air Pollution page under the Mold Abatement section. Mold contractors must complete the background information on the mold project before they are prompted to submit the relevant forms. Upon receipt of the filing, an email will be sent to the mold assessor and mold remediator affirming that their respective filings have been received. Mold contractors are required to provide the property owner with the filing receipt.

This filing requirement is not required for multiple dwellings under 10 units; irrespective of the size of the mold area.

For a multiple dwelling that is covered under Local Law 61 of 2018, where a violation has also been issued, the property owner is required to provide the following documents to the licensed mold contractors:

  • Cleaning mold with soap or detergent and water;

  • Cleaning any remaining visible dust from the work area using wet cleaning methods or HEPA vacuuming.
